Abstract

Abstract 1-Acylmethyl-2-(ω-hydroxyalkylamino) benzimidazoles were synthesized and their behavior under various conditions was investigated: at the thermolysis without solvent, at heating in DMF or in 2-aminoethanol, hydrohalic acids, and acetic anhydride, in the presence of chlorinating agents (SOCl 2, POCl 3). Depending on the reaction conditions derivatives were obtained of 1 H-imidazo [1, 2-a]-benzimidazole, 9 H-2, 3-dihydroimidazo ...
